Gunson's Colortune G4074, carburettor tuning kit. MSA1002

To Suit Vehicles with 14mm Sparkplug 

Ingenious kit which allows you to see the colour of the combustion in the cylinder head chamber by virtue of a glass topped spark plug.

This takes the guess work out of mixture adjustment as different fuel/air mixtures burn with different colours.

A full chart and instructions make this an easy to use kit.

One of the few kits that earns its cost back by saving fuel and money in a short time .
